(CNN) -- The Grimsvotn volcano under the Vatnajokull glacier in Iceland was erupting Saturday, according to the Icelandic Meteorological Office.

A dark cloud of smoke was rising from the glacier, and scientists were flying over the scene to evaluate the event, according to CNN affiliate TV2 Iceland.

The last eruption of the volcano was in 2004, TV2 Iceland reported.

Last year, another Icelandic eruption, of the volcano Eyjafjallajokull, attracted worldwide attention after its ash cloud disrupted air travel across Europe.

Sitrun Kapitola, manager of the Islandia Hotel Nupar, which is close to Saturday's eruption, said she could see a cloud of smoke over the mountains, and ash was falling around the hotel.

Police were telling her and others that there was no need to evacuate and there was nothing to fear, Kapitola said.

"We see it very well," she said.

"It's nothing compared to the other one," she added, referring to last year's dramatic Eyjafjallajokull eruption.

Tourists at the hotel were excited to see the eruption, watching the events unfold while eating dinner, she said.

"It happens every 10 years," she said. "It mostly produces water."

Grimsvotn is Iceland's most frequently active volcano. In 1783, a 16.7-mile fissure system from the volcano produced the world's largest known historical lava flow over a seven-month period, damaging crops and livestock, according to the Smithsonian National Museum of Natural History. A resulting famine led to the loss of one-fifth of Iceland's population, according to the Smithsonian website.

Well we're still here and everything is fine... It's too bad that Iceland and the Philippians had some natural occurrences happen today... It's going to give wind to the "believers." I wonder how long this will drag on for now, or when Mr. Camping will say that he found new documents proving that the Rapture will be in another 10 years... Too bad he won't be alive for that.

Oh man Mr. Camping needs to give it up already.How many times can someone be wrong about this and still get media play? At least I'll be able to get married in July now, so that's cool. His followers need to wake the fuck up... They're going to have nothing to come back to when this is all said and done.

Harold Camping looks like he could go any day now himself. Won't that be a sad sad day...
